OralHealthConcernsforPreteens

As if the preteen years didn’t give kids and their parents enough to think about, new oral health concerns loom on the horizon. Along with major changes to the body, brain and emotions, additional risk factors for tooth decay and gum disease appear during adolescence — the period of development starting around age 10 and extending through the teen years that marks the transition from childhood to adulthood.

Even with declining rates of tooth decay across the nation, the cavity rate remains high during adolescence. According to the American Academy of Pediatrics, 1 in every 5 adolescents has untreated tooth decay. What’s more, the onset of puberty — usually beginning around age 10-11 in girls and 11-12 in boys — brings changes in hormone levels that can affect gum health.

We all have millions of microorganisms in our mouth, representing hundreds of different species of mostly helpful, but some harmful, bacteria. Research has shown that total oral bacteria increases between ages 11 and 14, and new types of bacteria are introduced, including some that are not friendly to teeth and gums. Some unfamiliar microbes trigger an exaggerated inflammatory response to dental plaque, so gum bleeding and sensitivity are experienced by many children in this age group. In fact, “puberty gingivitis,” which peaks around age 11-13, is the most common type of gum disease found during childhood.

A combination of hormones, lifestyle changes and poor oral hygiene habits raises the risk of oral health problems among adolescents. A more independent social life may be accompanied by a change in eating habits and easier access to snacks and beverages that are sugary, acidic (like sports drinks and soda) or full of refined carbohydrates — none of which are tooth-healthy choices. And as children move toward greater independence, parents are less likely to micromanage their children’s personal care, including their oral hygiene routines. Good oral hygiene can keep dental plaque at bay, lowering the chance of having gingivitis and cavities. But let’s face it: Adolescents have a lot to think about, and keeping up with their oral health may not be top of mind.

To help your preteen stay on top of their oral health, keep healthy snacks at home for your children and their friends and make sure you are well stocked with supplies such as new toothbrushes, floss and toothpaste. In addition, most preteens (and teens) can benefit from gentle reminders about oral hygiene routines.

For optimal oral health through all stages of life, make sure your preteen keeps up with professional teeth cleanings and exams, and talk with us about whether fluoride treatments or sealants may be appropriate for your child.

IsYourSmileTooGummyHeresHowWeMightBeAbletoImproveit

Your gums not only support and protect your teeth they also help present them in a visually attractive way. But some people’s gums seem to stand out too much — what’s commonly called a gummy smile — which diminishes their smile appeal. There’s no precise definition, but as a rule of thumb we consider a smile too gummy if four or more millimeters (about an eighth of an inch) of the gums show.

Fortunately, there are some techniques to improve a gummy smile. Which technique is best for you, though, will depend on why the gums are prominent — and causes vary. For example, you could have a gummy smile because your teeth appear too short compared to your gums.

Permanent teeth normally erupt to about 10 mm of visible length. But less than that, say 8 mm, could skew the visible proportion of gums to teeth too much toward the gums. Teeth can also appear shorter due to accelerated wear caused by grinding habits. Another cause could be the amount of upper lip rise when you smile. The lip may rise too high in a condition called hypermobility. This could reveal too much of the gums when you smile.

It’s important then to match the treatment to the cause. For example, we can enhance the appearance of shorter teeth through a surgical procedure known as crown lengthening.├é┬áDuring this procedure a surgeon reshapes the gum tissues and underlying bone to expose more of the tooth’s length.

For upper lip hypermobility, we can restrict movement with Botox, a drug that paralyzes tiny parts of the involved muscles. This approach, though, will wear off in a few months — a more permanent solution is surgery to reposition the muscle attachments so as to prevent excessive movement.

If you’re concerned about a gummy smile, see us for a full examination and consultation. Once we know the reason why, we can offer a solution that will make your smile more attractive.
